IMPROVEMENT IN EXTENSION-TABLES.

Specification forming part of Letters Patent No. 167,331, dated August31, 1875; application filed February 2, 1875.

To all whom it may concern:

Be it known that I, FERDINAND GOLD- BACH, of Williamsburg, Brooklyn, inthe county of Kings and State ofNew York, have invented an ImprovedFall-Leaf Extension- Table; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the accompanying drawings forming part of this specification.

The invention relates to that description of fall-leaf extension-tablesin which the legs are attached to slides which form part of the body ofthe table. Their attached legs slide out bodily under the leaves orflaps.

The invention has for its object to produce an automatic operation ofthe slides of such tables; and to this end it consists in the novelapplication of coiled springs for forcing out the said slides under theleaves when permitted to do so by the simple act of raising the leavesby hand.

In the accompanying drawing, Figure 1 represents a central verticalsection on the line 0000, Fig. 3, of my improved table. Fig. 2 is asection on the same line with the fall-leaves extended. Fig. 3 is anunder view of the table extended.

The body of the table consists of a centerpiece and twoextension-slides. To this centerpiece A are fastened, at a suitabledistance from each other, two rails, a a, parallel to each other. Theinner and outer sides of these rails are provided with tongues, whichengage with the grooves in the side pieces B B of the extension-slides.To the end rails E E of the said slides, between the legs of the table,are secured longitudinal guide-rods b b for the springs c c. The one endof each of these springs presses against one of the rails E E,

while the other of each is supported by a stationary bearing-piece, O,fastened to the center-piece A of the table. The brace 0 serves at thesame time for a support of the guiderods b b, which slide in the former.The fallleaves D D, hinged to the center-piece A of the table, arrestthe action of the springs by their weight when depressed, but when thefall-leaves are elevated the action of the springs pushes the slides B Eand B E, which form parts of the body of the table and their attachedlegs under the flaps, and keeps the same elevated. This action isrendered easy by casters on the legs. In order to depress thefall-leaves it is necessary to thrust the slides inward until the leavesdrop, and by their weight check the action of the springs and keep theslides under the center-piece A of the table. The table, having thesprings combined with its extension-slides, which form parts of thetable body, possesses great advantages in strength and firmness over thetables which are extended by springs which are applied to mere slidingrods or bars or to an extra leg.

I claim-- 1. The combination, with the extensionslides forming parts ofthe table, of springs applied to the said slides, substantially asdescribed, for the purpose set forth.

2. The coiled springs c "0, the guide-rods b b, the bearing 0, incombination with the slides B E and B E, and the fall-leaves D D of thetable, all arranged and combined substantially as described, and for thepurpose set forth.

FERDINAND GOLDBAOH.
